ADJUSTABLE ARM SUPPRT FOR BEDSPRINGS.

Application filed October 24, 1927. Serial No. 228,139.

This invention relates to an adjustable arm support for bed springs, and more particularly to an adjustable support for use in connection with the coil type of bed springs.

Bedsteads such as now commonly found on the marlret, vary somewhat in width, depending on the type and construction of bedstead. 1n metal bedstead-s, which are often provided with angle iron side rails on which the usual bed spring is mounted, the distance between the angle iron side rails is often somewhat greater than the distance between the bed spring supporting side rails of a wooden bedstead, and it is consequently desirable to provide an adjustable means l for permitting mounting of a bed spring in either type of bedstead.

rl`he principal object of the present invention is, therefore, to provide an adjustable supporting` means for facilitating mounting of a bed spring on either a met-al or wooden bedstead. Other objects are to provide an adjustable supporting means which is provided with means for eectively locking the same in operative or supporting position; to provide locking means which is responsive to or rendered effective by the weight of the bed spring when the latter is mounted on a bedstead; to provide an adjustable support which will be effectively locked in the desired supporting position, but which will be readily adjustable to the desired position without the aid'of tools; and in general, to provide an improved support of the class described.

Further objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing in which we have described and illustrated a selected embodiment of the invention in connection with a coiled spring tvpe of bed spring and its manner of use in i connect-ion with bedsteads in which the bed spring supporting side rails are dilferently spaced apart.

In the drawings:

Fig, 1 is a cross section of a portion of a metal bed having an angle iron side rail and showing the manner of mounting a bed spring on the bedstead by means of my improved adjustable support.

Fig. 2 is a. plan of a portion of Fig. 1.

Fig. 3 is a section corresponding t-o a portion of Fig. 1, but showing the manner of mounting` a bed spring on a wooden bedstead in which the bed s? ring suppdrtinf side rails are closer together than in the metal bedstead of F ig. 1, and

Fig. 4 is a section on the line 4 4 of Fig. 3.

Referring now to the drawings, we have shown in Fig. 1 a portion of a bed spring including a main frame 10, which extends around the margin of the bed spring and between opposite sides of which, a plurality of spring supports, such as shown at 11, extend. These spring supports are secured to the main frame by suitable means such as rivets, indicated at 12. The main frame preferably consists of an angle iron member having a vertical flange 13 and a horizontal flange 14, and the spring supports preferably consist of strap metal members, each having a portion intermediate the opposite side members disposed with the width of the member lying in a substantially vertical frame as shown at 15, and its end portions twisted, as indicated at 16, so as to be horizontally disposed to facilitate mounting on the horizontal flange of the main frame.

Marginal coil springs such as indicated at 17, are secured in place on the horizontal end vportion of the spring support by suitable means such as clips 18, which are secured to the said horizontal end portion by means of rivets, or screws, as indicated at 19. The upper ends of the coil springs 17 are secured to a top border wire 20, in any suitable manner. Intermediate coil springs such as indicated at 21 are seated at their lower ends on the vertically disposed portion 15 of the spring support, and secured thereto by means of tie members 23. The intermediate coil springs 21 are preferably connected in any suitable manner adjacent their top coils to the top coils of adjacent springs. The springs are also connected intermediate their top and bottom coils, by means of helicals, such as shown at 24, to intermediate portions of the adjacent springs or to the main frame of the bed spring, a substantially horizontal coil being preferably provided in each spring for facilitating such intermediate connection.

In Fig. 1, we have have shown the bed spring mounted on an angle iron side rail 25 which constitutes part of a metal bedstead. rlhe means for mounting the bed spring includes an arm 26 which is slidably mounted in an aperture 27 provided in the vertical flange 13 of the main frame of the bed spring. The arm 26 is a. loose lit in the aperture 9,7, and is retained therein by means of a br clret 28, which is secured to the vertical flange of the main frame by suitable means such as riveting, as indicated at 29. |lhe outer end of the bracket is provided with an upwardly extending portion which is provided with notches 3l and 32 in its opposite edges, thereby providing a narrow neck portion 33, which is adapted to slidably lit in a slot 34 provided in the inner end portion of the arm 26. The slotted arm and bracket are assembled by turning the bracket to a position relative to the slot in the arm wherein the end oit' the bracket may be passed through the slot, and then turning the bracket relative to the arm f so as to cause the edges ot the arm at said slot, to enter he notches in the bracket. Such position for assembling the parts cannot be obtained when the parts are disposed in operative position relative to the vertical Hange and hence, the arm cannot accidentally be removed from the frame.

The arm 26 is provided with a plurality of upwardly projecting stops or abutments 35, 36 and 37, which are preferably formed by punching portions of the arm upwardly, as clearly shown at in F ig, l, and these stops or abutments are adapted to engage a portion of the vertical flange 13 of the main frame adjacent the top edge of the slot 2T, to prevent inward movement or adjustment of the arm when the bed spring is mounted on the side rail of a bedstead. The abut-ments are spaced longitudinally of the arm, and they are preferablyl arranged in staggered or oil"- set relation to each other, as clearly shown in Fig. 2.

' By an inspection of Fig. l, it will be readily understood that the weight of the bed spring is transmitted through the arm 26 to the side rail 25 of the bedstcad, the arm engaging spaced portions of the bed spring. As shown in F l, the arm 26 rests at its outer end on the horizontal flange of the side rail 25, and tenus to swing downwardly at its inner end about the edge of the side rail as a fulcrum. Such downward pivotal movement of the arm is prevented by engagement of the top of the abutment 36 with the under 'ace out the horizontal flange 14 of the main :trame and engagementol the under face or' the inner end of the arm 26 with the top face of the bracket member 28, as shown at 33.

rlhe aperture 2T in the vertical flange of the` main traine is of sulicient width to permit sliding of the punched out abutments ol the arm 26 therethrough, when the arm is to be moved inwardly for mounting the bed spring on a wooden bedstead. It will be readily understood that when the weight of the bed spring causes the arm 26 to swing about the inner edge of the side rail as a ulcrum, the abutment adjacent the outer face ot the vertical flange 13 of the main frame will be caused to move upwardly relative to the main frame so that it will engage the face of the vertical flange adjacent the slot, as clearly shown in Fig. l, where the abutment- 37 is shown in such engagement.

vWhen the bed spring is to be mounted on a wooden bedstead in which the supporting side rails are not spaced apart as far as are the side rails in a metal bedstead, the arm 26 is moved inwardly until, for example, as shown in Fig. 3, the abutment 35 is in position to engage the edge portion of the vertical flange 13 adjacent the top edge oit the slot 27 to thereby prevent further inward adjustment ot" the arm. ln Fig. 3 the parts of the bed spring are shown in the position in which they appear when mounted on a wooden bedstead, which includes a bed spring supporting rail 39, which is secured to an ornamental side rail 40. By an inspection of Fig. 3, it will be noted that the means for locking the arm 26 against inward movement is responsive to the weight of the bed sprino' which is ellective to move the outer end or the arm 26 upwardly relative to the main frame of the bed spring so that the abutment 35, orabutments 36 or 37, as the case may be, will engage the vertical ilange of the main frame, and will not pass through the aperture 27. n

lVe have thus provided an adjustable arm support for bed springs which is simple in construction, which will not readily become inoperative., and which is easily and quickly adjusted and eile'ctively locked in the desired position so that there is no danger of the bed spring slipping off the supporting rail of the bedstead.
